INTRODUCTION
The eGenix.com pyOpenSSL Distribution includes everything you need to
get started with SSL in Python.
It comes with an easy-to-use installer that includes the most recent
OpenSSL library versions in pre-compiled form, making your application
independent of OS provided OpenSSL libraries:

pyOpenSSL is an open-source Python add-on that allows writing SSL/TLS-
aware network applications as well as certificate management tools:

OpenSSL is an open-source implementation of the SSL/TLS protocol:

NEWS
This new release of the eGenix.com pyOpenSSL Distribution updates the
included OpenSSL version to the latest OpenSSL 1.0.1h version and adds
a few more context options:
New in OpenSSL
--------------
* Reenabled the SSLv2 support in the bundled OpenSSL libraries which
we had removed in 0.13.5, since removing the SSLv2 symbols resulted
in too many compatibility problems with existing code such as e.g.
>>> import OpenSSL
>>> import ssl
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "ssl.py", line 60, in <module>
import _ssl
ImportError: _ssl.so: undefined symbol: SSLv2_method
The ImportError is the result of using the 0.13.5 version of the
OpenSSL libs with an ssl module which was compiled against a system
version with SSLv2 support, effectively making the ssl module
unusable.
To protect against SSLv2 and SSLv3 downgrade attacks, please make
sure you setup the SSL context to disallow using SSLv2 and SSLv3,
e.g.
context = SSL.Context(SSL.SSLv23_METHOD)
context.set_options(SSL.OP_NO_SSLv2 | SSL.OP_NO_SSLv3)
New in pyOpenSSL
----------------
* OpenSSL.__version__ is now updated to the distribution version
rather than left at "0.13" as it was in previous releases. It now
shows "0.13.6" for this release.
* Emphasized on the need to "import OpenSSL" early to prevent Python
from loading the system OpenSSL libraries instead of the embedded
ones. Be sure to read the section Loading the embedded OpenSSL
Libraries of the documentation for details on how to make sure that
the embedded libraries are loaded:
http://www.egenix.com/products/python/pyOpenSSL/doc/#LoadingOpenSSL
Please see the product changelog for the full set of changes:

pyOpenSSL / OpenSSL Binaries Included
-------------------------------------
In addition to providing sources, we make binaries available that
include both pyOpenSSL and the necessary OpenSSL libraries for all
supported platforms: Windows x86 and x64, Linux x86 and x64, Mac OS X
PPC, x86 and x64.
We've also added egg-file distribution versions of our eGenix.com
pyOpenSSL Distribution for Windows, Linux and Mac OS X to the
available download options. These make setups using e.g. zc.buildout
and other egg-file based installers a lot easier.
